Apple announced on Tuesday that iOS 7 will be publicly available on September 18th. The revamped OS moves completely away from the realistic designs of the past six generations, dropping almost all “artificial shadows” (as Apple SVP Craig Federighi called them), gloss, and even button borders. Instead, the Jony Ive-inspired interface features an entirely rethought design language that focuses heavily on large icons, lightweight fonts, whitespace, transparency, and conservative use of color.

We previously took a look at what some of Apple’s own in-house apps could look like when redesigned for iOS 7. During Apple’s September 10th event, Federighi flashed up a slide displaying the upcoming iOS 7 updates for many third-party applications. None of the apps were labeled, but we’ve tracked down names for most of them.

Google’s Vic Gundotra just announced on his Google+ page a host of new Hangouts features meant to “go beyond the status update”. In short, you can now hangout on any post (an invitation will be added to the comments), call any phone number in the world and conference in anyone (free calling to US and Canada, international calling rates are “super, super low”), plus initiate a hangout session from the official Google+ iOS app by tapping the new hangout icon.

The executive also shared an interesting milestone for Hangouts on Air, saying “hundreds of people” whitelisted as part of their trial now have the ability to broadcast their hangouts to the world. “Our goal is to enable this for everyone on the planet”, Gundotra noted. You will also be able to automatically record a Hangouts on Air session and upload it to a private YouTube account for later viewing. These features require a new Google+ app, “coming soon” to the App Store. The official Google blog has more information.

Tab for Google+ is an app available on the Mac App Store that brings Google+’s web functionality to the Mac desktop. The app is available for free and offers just about every feature plus.google.com offers — except Hangouts. Upon logging in via your Google account, you’ll be greeted with the main sections of the app: Streams, Photos, Circles, Profile and Notifications.

The sections follow suit with the functionality of the website. Streams and Photos curates content from the people you’re following. Circles allows you to see your list of circles and the content coming in from each specific one. Lastly, Notifications let’s you know what’s going on with your account.

Of course, this application won’t replace Google+’s website, rather it’s just a nice app that sits in your applications bar to view while you work. Perhaps if the website is more your thing, check out Google+ for Mac which is essentially just a browser window. We’re hearing the developer is working to make it native though.
